In this study, we performed whole effluent toxicity(WET) test and compared the biological component analyses tests for some streams into which wastewater treatment plant effluents are discharged. The test procedures for the WET test and the biological component analysis were conducted according to U.S. EPA guidelines and the Ohio EPA wading method. The WET tests based on the test species of D. manga and S. capricornutum All treatment plants showed a S. capricornutum toxicity, and at 7 sites, except A and J, we could observe a D. magna toxicity. The highest toxicity was observed at site D and this were followed by E and F. The biological component analyses applied to the effluent discharged stream. We found that total species were low at sites C1, D1 and J1 and the low number of total individuals were observed at sites A1, C1, E1, H1, and J1 compared to the controls and other sites. The species richness was low at sites A1, B1, C1, D1, and J1. The species change was evident at site D(D1) and the tolerant species was predominant. The biological analyses and WET tests suggested that the effluents resulted in massive ecosystem impact.

This study was identified the survey period and emergence of main species of dragonfly species, an indicator species that can identify the characteristics of wetland ecosystem. I surveyed the species and population of dragonflies once every two weeks from May 2015 to October 2016(29 times). From January to March, November and December were excluded from the cluster classification because the dragonflies were not observed. In April and October, the species was emerged but it was not suitable because it could not represent the time of the seasons. When we divide by month, it was able to judge from April to June as spring. Except the May, there were some changes due to rainfall and temperature, and sometimes June was included in the summer season. June, July and August correspond to summer, and September and October fall in Autumn. In June and October, the change was expected due to the effects of temperature and so it was judged as a partial fit. Looking at the change of the species, Coenagrion johansson and Paracercion calamorum were increase at the spring, and then Crocothemis servilia mariannae, Paracercion calamorum, Anax nigrofasciatus, Lyriothemis pachygastra, Orthetrum melania were abruptly enlarge in summer. At last, Sympetrum kunckeli, Lestes temporaris tended to be higher in Autumn.

This study investigated the correlation between the trees planted on the slope of the first landfill where the landfill was completed and the soil environment. 69 plots (($7{\sim}20m{\times}5{\sim}20m$) were planted with 26 kinds of major trees in the first landfill slopes for vegetation survey. The survey was conducted from 2007 to 2009. Soil analysis from 2007 to 2008 was made on the basis of the injured index and the indicator species were selected. Depending on the rate of growth of the indicator species, seven survey locations were selected for soil sample analysis. 10 tree species appeared to adapt to the landfill environment. Among them, the coniferous trees were Pinus thunbergii (Seedling) and Juniperus chinensis and the deciduous trees were Quercus aliena, Salix preudo-lasiogyne, Castanea crenata (Seedling), Prunus armeniaca var. ansu, Quercus acutissima, Chionanthus retusus, Liriodendron tulipifera (Seedling) and Celtis sinensis. 8 species of trees did not adapt well to the landfill environment. Among them, two kinds were coniferous, the other six kinds were deciduous. In addition, judgment on the other 8 species of trees as to whether they adapted well or not was postponed. The species for which judgment was postponed included one coniferous tree and seven deciduous trees. Indicator species of injured index was the species that have more than 25 % of the defect. The soil was collected from where Catalpa ovata, Sophora japonica, Albizzia julibrissin and Acer palmatum were planted for analysis. According to the soil analysis, the soil pH showed that the soil was alkaline. Regarding the three phases of the soil, most sample soil showed 60 % for the solid phase or 55 % for the solid phase but with less than 10 % of gas phase. The organic matter content was found to be 0.14 to 2.52 %.

For conservation of biodiversity, we designate and manage the major areas that are habitats of organisms as ecosystem protected areas. It is necessary to evaluate the biodiversity of protected areas relatively in order to establish strategies to protect and secure the biodiversity of protected areas. In this study, we selected evaluation indicators by which we can compare objectively the biodiversity of protected areas corresponding to forest ecosystem, and applied them to Mt. Jiri and Mt. Bukhan National Parks. We reviewed literatures to select evaluation criteria. Frequently mentioned criteria and the structure of the forest which plays an importantrole of forest biodiversity were selected as the evaluation criteria. As the result, the selected evaluation indicators were 7-species diversity, species richness, evenness, rarity, disturbance species, indigenous species, and forest structure. In Mt. Jiri and Mt. Bukhan National Parks, species diversity were 3.492 and 2.943, species richness were 8.998 and 9.793, evenness were 0.849 and 0.680,rarity were 11.976 and 10.783, and disturbance species index were 0.214 and 0.357 respectively. Both national parks had abundant indigenous species and showed various forest physiognomies and stable 4-layer structure. It was found that crown density was higher in Mt. Jiri. Most indicators were implied high biodiversity in Mt. Jiri and Mt. Bukhan national parks.

Most wetlands worldwide have suffered from extensive human exploitation. Unfortunately they have been less explored compared to river and lake ecosystems despite their ecological importance and economic values. This is the same case in Korea. This study was aimed to estimate the assemblage attributes and distribution characteristics of benthic macroinvertebrates for fifty wetlands distributed throughout subtropical Jeju Island in 2021. A total of 133 taxa were identified during survey periods belonging to 53 families, 19 orders, 5 classes and 3 phyla. Taxa richness ranged from 4 to 31 taxa per wetland with an average of 17.5 taxa. Taxa richness and abundance of predatory insect groups such as Odonata, Hemiptera and Coleoptera respectively accounted for 67.7% and 68.2% of the total. Among them Coleoptera were the most diverse and abundant. Taxa richness and abundance did not significantly differ from each wetland type classified in accordance with the National Wetland Classification System. There were three endangered species (Clithon retropictum, Lethocerus deyrolli and Cybister (Cybister) chinensis) and several restrictively distributed species only in Jeju Island. Cluster analysis based on the similarity in the benthic macroinvertebrate composition largely classified 50 wetlands into two major clusters: small wetlands located in lowland areas and medium-sized wetlands in middle mountainous regions. All cluster groups displayed significant differences in wetland area, long axis, percentage of fine particles and macrophyte composition ratio. Indicator Species Analysis selected 19 important indicators with the highest indicator value of Ceriagrion melanurum at 63%, followed by Noterus japonicus (59%) and Polypylis hemisphaerula (58%). Our results are expected to provide fundamental information on the biodiversity and habitat environments for benthic macroinvertebrates in wetland ecosystems, consequently helping to establish conservation and restoration plans for small wetlands relatively vulnerable to human disturbance.

We developed an evaluation index for selecting pet insect species. As an expert opinion survey, the Delphi method was used to establish evaluation items. Using AHP (analytic hierarchy process), evaluation criteria for selecting pet insects were proposed. And then based on application testing, we established a scoring system.

연구개발활동에 관한 평가를 수행할 때, 가장 많이 사용되어 온 방법이 동료평가(peer review)방법이지만, 최근에는 동료평가가 가지는 문제점을 보완하기 위해 정량지표(bibliometric indicator)의 도입이 다각적으로 검토되고 있다. 여기서는 이를 위해 새로운 정량지표로서 첫째, 동료평가와 정량지표의 점수 배분비율로 각각 $70\%$와 $30\%$로 하고 둘째, 과거 5년 간 가장 우수한 논문 10편만을 대상으로 정량지표를 작성하며 셋째, 각 논문이 게재된 저널이 속한 분야 저널들의 impact factor 순위를 백분율로 적용하여 이에 따른 가중치를 적용하는 방식이 바람직하며 넷째, 논문에서의 저자 역할에 따라 점수를 차등화하고 공동저자의 논문 실적이 주저자의 논문실적에 의해 결정되도록 하는 방식을 제안하고 있다. 이와 같은 정량지표는 과거의 정량지표가 가지고 있었던 한계를 상당 부분 극복할 수 있을 뿐 아니라 동료평가를 보완하는 방법으로 사용될 수 있다.
